Tamagotchi

⚠️ Experimental — generated with no human supervision. This realm was produced automatically by an MCP-driven agent to exercise the gno MCP server and tooling, and to generate test content for gno compilers, linters and formatters. Not audited. Not for production. Full context & folder README: r/moul/x/daily

A tiny on-chain virtual pet. Hatch one, then keep it alive by feeding, playing, and letting it sleep — hunger, happiness, and energy all decay with block height, so neglect (or just forgetting to check in) eventually kills it. Hatching a new pet after a death keeps your lifetime feed/play/death counts, so the leaderboard rewards long-term care rather than a single lucky run.

Realm: gno.land/r/g12cs4cehujpffpjpywmkqj43m6u5ya53nj69sjz/tamagotchi

Example calls

maketx call ... -func Hatch -args "Fluffy"     # start a pet
maketx call ... -func Feed                     # -30 hunger, +5 energy
maketx call ... -func Play                     # +20 happiness, -10 energy, +5 hunger
maketx call ... -func Sleep                    # +40 energy, +5 hunger

Render("") lists every pet ever hatched with alive/dead status and lifetime stats. Render("<owner-address>") shows one pet's detail card.

Toolchain status

gno test . passes (10/10 tests) against ~/p/gh/gnolang/gno as GNOROOT. Uses only chain/runtime, sort, strconv, and the kept gno.land/p/nt/avl/v0 / gno.land/p/nt/testutils/v0 packages per the sapphire stdlib reference. Panic paths are tested through non-crossing helper functions (hatch, feed, play, sleep) rather than through the exported cur realm entry points, since panics raised inside a realm-crossing call aren't recover()-able from the caller on this toolchain version.

Part of moul/gno-contracts — moul's versioned gno.land contracts. See the repository for the full catalog, build/test tooling, and usage.

Overview

Package tamagotchi is an on-chain virtual pet. Hatch one, then keep it alive by Feeding, Playing and letting it Sleep — hunger, happiness and energy all decay with block height, and neglect too long kills the pet. Hatching again after a death starts a fresh pet but keeps your lifetime stats, so the leaderboard rewards long-term care, not just luck.

Functions 5

func Feed

crossing Action 
1func Feed(cur realm) string
source

Feed reduces hunger and gives a small energy boost.

func Hatch

crossing Action 
1func Hatch(cur realm, name string) string
source

Hatch creates a new pet for the caller. Lifetime feeds/plays/deaths carry over from any previous pet so the leaderboard tracks long-term care.

func Play

crossing Action 
1func Play(cur realm) string
source

Play boosts happiness at the cost of energy and a bit of hunger. Refuses to run a tired pet into the ground — rest first.

func Render 

1func Render(path string) string
source

Render shows either every pet ever hatched (path == "") or a single pet's detail card when path is a bech32 owner address.

func Sleep

crossing Action 
1func Sleep(cur realm) string
source

Sleep restores energy at the cost of a little hunger.
